True
experimental research design is a type of research design that involves the
manipulation of one or more independent variables to observe the effect on a
dependent variable, while controlling for other variables that could
potentially affect the outcome. It is considered to be the gold standard in
research because it allows for causal inferences to be drawn between the
independent and dependent variables.
In a
true experimental research design, participants are randomly assigned to
different groups: an experimental group that receives the intervention or
manipulation, and a control group that does not. The two groups are then
compared to see if there is a statistically significant difference in the
dependent variable, which is the outcome of interest.
To
enhance the internal validity of the study, researchers often use double-blind
procedures, where both the participants and the experimenters are unaware of
which group the participants have been assigned to. Additionally, researchers
may use randomization procedures to ensure that any individual differences
between participants are evenly distributed across the groups.
Overall,
the true experimental research design is a powerful tool for investigating
cause-and-effect relationships between variables, but it can be
resource-intensive and may not always be feasible in certain research settings.
